Which teams are likely to be most active in free agency? We rank them 1-32 based on their needs, historical behavior and resources (each club's available cap space as of Friday, according to USA TODAY Sports research, is listed in millions):

1. Cleveland Browns ($47.5M): They've got the money, a new owner eager to make a splash, no core players of their own to re-sign yet plenty of areas to address. A cornerback and pass-rushing linebacker for a defense switching back to the 3-4 front could head the list, though it'd also be nice to give QB Brandon Weeden - or whoever is taking the snaps in 2013 - an established receiver.

2. Miami Dolphins ($31.3M): They had even more cap space before re-signing WR Brian Hartline, backup QB Matt Moore and putting the franchise tag on DT Randy Starks. But Miami still needs to get second-year QB Ryan Tannehill more help. Luring Mike Wallace or Greg Jennings, who played for coach Joe Philbin in Green Bay, to pair with Hartline makes a ton of sense. RB Reggie Bush and LT Jake Long are among unsigned Dolphins, but Long can be capably replaced by second-year RT Jonathan Martin. Another pass rusher for a defense that needs additional playmakers could trump Bush and Long.

3. Tampa Bay Buccaneers ($32.2M): They opened the checkbook last year for WR Vincent Jackson and all-pro G Carl Nicks. The Bucs have the wherewithal to do more now, and their league-worst pass defense should be the priority. That means getting another corner - Sean Smith? Dominique Rodgers-Cromartie? - and/or a pass rusher. A rental like John Abraham could make more sense than a long-term deal to re-sign DE Michael Bennett.

4. Indianapolis Colts ($37.5M): GM Ryan Grigson also has plenty on the free agency debit card. We'd expect him to be judicious, though his club needs help in the trenches on both sides of the ball. Pass rusher Paul Kruger, one of coach Chuck Pagano's charges in Baltimore, would be a perfect replacement for departed Dwight Freeney.

6. Philadelphia Eagles ($34.2M): Their financial reserves will grow if expensive CB Nnamdi Asomugha is set free. The entire defense may need an overhaul - the secondary underperformed, and the front seven is converting to a 3-4 alignment that isn't ideal for many incumbents. New coach Chip Kelly may want to stockpile some of his funds until he can better assess what his high-tech offense requires at the NFL level.

7. New England Patriots ($26.4M): Clearly in win-now mode, QB Tom Brady's restructured contract should enable the Pats to more easily re-sign WR Wes Welker. Keeping RT Sebastian Vollmer also seems rather important but may be weighed against the need to re-up Aqib Talib or another comparable corner. If Brandon Lloyd is cast off, another field-stretching receiver becomes a priority.

8. Buffalo Bills ($21.9M): They've been shedding salaries and have a nice fund at their disposal even after franchising FS Jairus Byrd and re-signing CB/KR Leodis McKelvin over the weekend. Keeping topflight G Andy Levitre would keep an underrated O-line intact. But new defensive coordinator Mike Pettine will surely seek new parts, and the wideout corps is in shambles after Stevie Johnson.

9. Seattle Seahawks ($15.4M): A seemingly loaded team has money to ice the cake, even after trading for WR Percy Harvin. Pass rush is an issue after DE Chris Clemons tore an ACL in January, so this could be a perfect landing spot for a veteran like Freeney, Abraham or Osi Umenyiora.

10. Atlanta Falcons ($20.3M): After parting with Abraham, CB Dunta Robinson and RB Michael Turner, GM Thomas Dimitroff has more flexibility, but he rarely looks outside the building. That was good news for Pro Bowl SS William Moore, who re-signed for five years Saturday, and could be for unsigned LT Sam Baker and CB Brent Grimes. But Dimitroff is also trying to squeeze one more year out of TE Tony Gonzalez, who would needs a new deal, and must save up for QB Matt Ryan's second contract.

11. Tennessee Titans ($18.6M): After allowing a franchise-worst 471 points in 2012, the defense could obviously use some help - perhaps a corner to fill the void left last year by Cortland Finnegan. QB Jake Locker could use better blocking and wouldn't mind seeing talented TE Jared Cook brought back.

12. Minnesota Vikings ($14.8M): If they plan to keep riding RB Adrian Peterson, they better re-invest in stalwart RT Phil Loadholt and Pro Bowl FB Jerome Felton. Landing Jennings would be a coup (and a great way to hurt the rival Packers), but some kind of wideout upgrade would obviously benefit Peterson and disgruntled Percy Harvin.

13. Baltimore Ravens ($10.7M): Though QB Joe Flacco's $120.6 million pact is done, GM Ozzie Newsome knows he can't afford to keep the champs intact. That means free agents Kruger and CB Cary Williams may have to move on and possibly even WR Anquan Boldin, who's currently under contract for one more year. Expect Newsome to make a strong run at ILB Dannell Ellerbe while trying to hang on to FS Ed Reed, too. Re-signing LT Bryant McKinnie would be a bonus.

14. Kansas City Chiefs ($17.8M): With the pending acquisition of QB Alex Smith, the re-signings of WR Dwayne Bowe and Pro Bowl P Duntin Colquitt and the franchise tag they hung on LT Branden Albert, most of the Chiefs' work is done. But they did extract a heavy pay cut from DE Tyson Jackson, dumped starting RT Eric Winston and will probably soon release QB Matt Cassel, moves which helped them woo Robinson. Further help, maybe for the D-line, could be on the way.

15. Jacksonville Jaguars ($28.1M): They've got the cash to throw at their myriad problems, but why? New GM David Caldwell might be wise to extend LT Eugene Monroe's deal, but he can largely wait on the crown molding for later years after he lays a talent foundation through the draft.

16. Chicago Bears ($7M): As badly as they need to bolster the offensive line, DT Henry Melton's $8.5 million franchise tag currently limits what they can spend for bona fide blockers like Long and Andre Smith.

17. Houston Texans ($8.3M): Could this be the year they get a No. 2 wideout who can really take heat off Andre Johnson? Given their desire to re-sign S Glover Quin, FB/TE James Casey - perhaps OLB Connor Barwin if room can be made - and the need to get a kicker and punter all on a tight budget ... no.

18. Washington Redskins ($-2.1M): There's little doubt owner Dan Snyder would love to fuel up Redskins One and let it swoop around the country picking up better bodyguards for Robert Griffin III (and remember, they don't own a first-round draft pick this year). But a lot of other cuts must be made or money re-allocated first if that's going to happen while the 'Skins continue to work off the remainder of last year's $36 million cap penalty.

19. San Diego Chargers ($10M): Another team that needs to fortify the front five in front of franchise QB Philip Rivers but currently doesn't have the dough to make it happen. The Bolts really should try to at least keep G Louis Vasquez.

20. Dallas Cowboys (-$6.8M): They've spent recent weeks just trying to get under the cap while creating enough wiggle room to franchise pass rusher Anthony Spencer. With more trimming yet to do, don't expend them toss money around like they did in 2012. Besides, locking QB Tony Romo into an extension is their main concern.

21. Denver Broncos ($7.6M): Not a whole lot more they can do after franchising all-pro LT Ryan Clady, a move they had to make. One pipe dream would be replacing Brandon Stokley in the slot with Welker or Amendola, but that's likely to remain a fantasy given the depth infusion the defense needs.

22. Green Bay Packers ($19.3M): It'd sure be nice to improve the run game. But GM Ted Thompson, not a fan of free agency anyway, needs to keep amassing cap room in order to pay QB Aaron Rodgers, OLB Clay Matthews and NT B.J. Raji in 2014, if not sooner.

23. Detroit Lions ($6.7M): They're on the verge of losing a chunk of their roster and don't have the means to keep players like DE Cliff Avril, RT Gosder Cherilus or FS Louis Delmas. GM Martin Mayhew may have to re-do more deals of his current players just so he can fill out the depth chart.

24. San Francisco 49ers ($5.2M): There's not much cap space, which is why Goldson wasn't tagged. But they could have up to 15 draft choices once the supplemental picks are allotted. Maybe they get their star safety back, but look for the Niners to be more active in a trade market where they've already spun off Alex Smith.

25. New Orleans Saints (-$6.6M): They still have work left before complying with the cap. If they manage to re-sign LT Jermon Bushrod when all is said and done, consider this a successful offseason.

26. New York Giants ($10.1M): They already took care of LT Will Beatty, picked up DT Cullen Jenkins off the street and still need to work something out with restricted free agent WR Victor Cruz. Otherwise, it's mostly about the bargain bin and draft for GM Jerry Reese.

27. St. Louis Rams ($9.6M): Their cap is fairly snug, too, which could make Amendola a former Ram. Steven Jackson voiding the final year of his deal helps, but will he come back at a reduced rate? Coach Jeff Fisher has never been one to rely on outside free agents, and he and GM Les Snead still need to budget for two first-round rookie salaries this year anyway.

28. New York Jets ($6.3M): Historically, they've loved being shoppers. But anticipate new GM John Idzik to keep cleaning house and worry about redecorating down the road.

29. Oakland Raiders ($6.2M): DT Richard Seymour and P Shane Lechler are on the way out, but there are still a few inherited millstone contracts around GM Reggie McKenzie's neck. Oakland might be in position to start working its way up from rock bottom next year.

30. Arizona Cardinals ($3.3M): The O-line is screaming for reinforcements, but the Cards' wallets are virtually empty. Bruce Arians and the new regime have the luxury of patience anyway and will surely try to rebuild the pass game and pass blocking via the draft.

31. Pittsburgh Steelers (-$1.4M): Combine a battle with a bloated cap - it claimed former defensive MVP James Harrison on Saturday, getting the Steelers out of the red - with a historic aversion to free agency, and you can bet GM Kevin Colbert won't be making many phone calls.

32. Carolina Panthers (-$3.5M): Ditto for new GM Dave Gettleman, who can take this time assessing some of the questionable contracts he inherited. But after spending years earning his stripes with the Giants, expect Gettleman to build from within rather than chase outsiders now or in the future.
